COAL-WASHER.

Specification of Letters Patent.

Patented Jan. 15, 1907.

r- -mication filed September 4.1906. v Serial No. 333,074.

To aZZ whom, it 712,04 concern.-

Be it known that I, IWILLI M MILLER DUNCAN, a citizen of the United States of America, residing in Alton, in the county of Madisonand State of Illinois, have invented certain new and useful Improvements in Coal-I/Vashers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to take-up means for coal-washers, whereby the degree of lateral motion of the washer-jig is restricted to provide against undue motion of this character and consequent injury to the operating mechanism by which the rise-and-fall motion of the jig is produced, The desired result is accomplished by providing a peculiar arrangement of adjustable wearplates, against which the coal-washer jigs operate,

and means for adjusting said plates to secure only the desired freedom between the jigs and said adjustable wear-plates and compensate for the wear upon the wear-plates incident to the operation of the coal-Washer.

Figure I is a top or plan view of a coalwasher having my improvement applied thereto, the upper portion of the jig-operating means being omitted. Fig. II is a vertical longitudinal section taken on line II II, Fig. I. Fig. III is an enlarged vertical crosssection taken through the washer.

1 designates the washing-tank, such as commonly used in coal-washers and to which a chute 2, through which the coal is delivered, leads. The washing-tank. is surmounted by a frame 3.

4 represents shafts journaled in suitable boxes mounted on the frame 3 and having fixed thereto eccentrics 5. The eccentrics are surrounded by straps 6, and from these straps are suspended hangers 7, that swingingly support the jig 8 through the medium of rods 9, journaled in said jig. The jig is provided with the usual inclined perforated bottom 10 and foreign-matter outlet 11.

12 designates a gate that controls the outlet 11, and which is operated through the medium of a connecting-rod 13, that is connected' to a bell-crank lever 14, which in turn receives the connection of a connectingrod 15, that is actuated by a swinging plate 16, against which the coal strikes as it is delivered from the chute 2 into the jig 8.

No invention per se is herein claimed for the parts thus far described, they being shown and described in Letters Patent of the United States No. 783,249, issued to me February 21, 1905, and to which reference is made for a more complete understanding of the utility and operation of the parts.

At the outer side of one of the side walls of the jig 8 is a wear-plate 17, and opposite this plate upon the facing washing-tank wall is a wear-plate 18, the former plate being designed to ride against the latter plate during the rise-and-fall motion of the jig 8. The other side wall of the jig 8 has fixed to it at its outer. side a wear-plate 19, (seen most clearly in Fig. III,) the plate being preferably attached to the jig-wall by bolts 20.

21 designates a wear-plate that opposes the wear-plate 19. This wear-plate is supported at the end of and carried by a laterally-movable yoke or carrying member 22, to which the plate is preferably secured by angle-strips 23. The movable yoke or carrying member 22 is loosely positioned in an aperture 1 in the Washing-tank wall adjacent to the side of the jig which carries the wearplate 19, and said member is provided with an inclined outer portion 22.

24 is a wedge-shaped adjustment member or block having one of its faces inclined and arranged in contact with the inclined portion of the wear-plate-carrying member 22 and adapted to be shifted relative to said carrying member for the purpose of adjusting the movable wear-plate 21 relative to the adjacent jig-carried wear-plate 19. The adjustment member 24 is located between the wearplate-carrying member 22 and the member 3 of the coal-washer frame, and said frame member serves to prevent outward movement of the adjustment member and cause it to act positively against the wear-platecarrying member when it is shifted relative thereto in order that the desired adjustment of the wear-plate-carrying member may be secured. A wear-plate 25 is preferably mounted against the portion of the frame member 3 against which the adjustment member 24 slides for the purpose of preventing wearing of said frame member by said adjustment member. The adjustment member is preferably shifted through the medium of a setting-rod 26, that is attached at one end to the adjustment member and extends through a surmountin member of the frame of the washer, the rod being equipped with an adjustment-nut 27. It is obvious that any desired number of the adjustable wearplates 21 and adjustment members for moving said adjustable wear-plates may be utilized. In the washer herein illustrated I have shown three sets of said parts.

While I have shown and described my take-up means as located at only one of the side walls of the jig of a coal-washer, it is obvious that such means may also be provided at the opposite side wall of the jig, and, fur thermore, that the take-up means may be also provided at the ends of the jig without departing from my invention.

I claim 1. In a coal-washer the combination of a washing-tank having a wear-plate at one side and an aperture at the other side, a jig, having wear-plates, a laterally-movable carrying member having a wear-plate at its inner end, and slidable through the aperture in the tank, and means for adjusting said carrying member with its wear-plate substantially as set forth.

2. In a coal-washer the combination of a washingtank having a wear-plate at one side and an aperture at the other side, a jig, wearplates carried by said jig, a laterally-movable carrying member having a wear-plate at its inner end, and slidable through the aperture in the tank, and means for adjusting said carrying member with its wear-plate rela tively to the adjacent jig-carried wear-plate, substantially as set forth.

3. In a coalwasher the combination of a washing-tank having a wear-plate at one side and an aperture at the other side, a jig, having wear-plates, a laterally-movable carrying member having a wear-plate at its inner end,

opposing one of the wear-plates of said jig, and having an inclined portion at its outer end and slidable through the aperture in the tank, a wedge-shaped adjustment member opposing the inclined portion of said carrying member, and means for adjusting said adjustment member, substantially as set forth.

4. In a coal-washer the combination of a washing-tank having a wear-plate at one side and an aperture at the other side, a jig, having wear-plates, a laterally-movable carrying member having a wear-plate at its inner end, opposing one of the wear-plates of said jig, and having an inclined portion at'its outer end and slidable through the aperture in the tank, a wedge-shaped adjustment member opposing the inclined portion of said carryin member, and an adjustment-rod connected to said adjustment member, substantially as set forth.

5. The combination of awashing-tank having a wear-plate at one side and an aperture at the other side, a jig having wear-plates, a carrying member having an inclined portion at its outer end and slidable through the aperture of the tank, a wear-plate having anglestrips by which it is secured to the inner end of the carrying member, a frame member having a wear-plate, a wedge-shaped adjustment member located between the inclined portion of the carrying member and the wear-plate of the frame member, and means for adjusting the adjustment member.
